We're dividing 49159412 by 644 
We want to divide 49159412 by 644.

Step 1:
644 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 644

Advancing to step 2:
When dividing 49 by 644, we get 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 644

On to step 3:
644 goes into 491 0 times with a remainder of 491.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 491 leaves us with 491.
Grab the next digit (5) from the dividend, add it to 491, then carry on: 4915 / 644

Let's proceed to step 4:
644 goes into 4915 7 times with a remainder of 407.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 4508 away from 4915, we end up with 407.
Grab the next digit (9) from the dividend, add it to 407, then carry on: 4079 / 644

Moving on to step 5:
The number 644 fits into 4079 6 times, leaving a remainder of 215.
Put 6 as the next digit of the answer. 
Result so far: 76.0
The remainder is 215 after subtracting 3864 from 4079.
Take the next digit (4) from the dividend and append it to 215, then repeat: 2154 / 644

Moving on to step 6:
When dividing 2154 by 644, we get 3 with a remainder of 222.
Write down 3 as next digit of the result. 
Result so far: 763.0
If we take 1932 away from 2154, we end up with 222.
Include the next digit (1) from the dividend after 222, then repeat: 2221 / 644

Let's proceed to step 7:
When dividing 2221 by 644, we get 3 with a remainder of 289.
Write down 3 as next digit of the result. 
Result so far: 7633.0
If we subtract 1932 from 2221, we get 289.
Take the next digit (2) from the dividend and append it to 289, then repeat: 2892 / 644

Step 8:
If we divide 2892 by 644, we get 4 and a remainder of 316.
Put 4 as the next digit of the answer. 
Result so far: 76334.0
If we subtract 2576 from 2892, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 9:
644 goes into 3160 4 times with a remainder of 584.
Record the quotient 4 as the next digit in the result. 
Result so far: 76334.4
If we subtract 2576 from 3160, we get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 10:
When dividing 5840 by 644, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 76334.49
Subtracting 5796 from 5840 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
440 divided by 644 is 0 with a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 76334.49
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 12:
The number 644 fits into 4400 6 times, leaving a remainder of 536.
The next digit of our result is 6. 
Result so far: 76334.4906
The remainder is 536 after subtracting 3864 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Moving on to step 13:
644 can be fit into 5360 8 times, resulting in a remainder of 208.
Put 8 as the next digit of the answer. 
Result so far: 76334.49068
Subtracting 5152 from 5360 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 14:
The number 644 fits into 2080 3 times, leaving a remainder of 148.
Write down 3 as next digit of the result. 
Result so far: 76334.490683
Subtracting 1932 from 2080 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 15:
644 goes into 1480 2 times with a remainder of 192.
The next digit of our result is 2. 
Result so far: 76334.4906832
Subtract 1288 from 1480 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 16:
644 goes into 1920 2 times with a remainder of 632.
The next digit of our result is 2. 
Result so far: 76334.49068322
If we take 1288 away from 1920, we end up with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

After the division, we end up with 76334.49068322 and a remainder of 6.32e-07.
